Dark Star Orchestra

The free summer concert series kicks off its new season with this Chicago-based Grateful Dead tribute band. Dark Star Orchestra formed in 1997 as a result of co-founder John Kadlecik’s idea to perform complete shows pulled from among the nearly 2,500 concerts the Dead played from 1965 to ’95. Dark Star shows often presents the complete original set list, song by song and in order. A free afterparty follows featuring Madison’s the Grasshoppers (Majestic, 11 pm).
